Neurogenic detrusor overactivity (NDO) often occurs after spinal cord injury, which often causes urinary tract infection, vesi-coureteral reflux, or even renal failure, and seriously impacts on the patient's quality of life. This paper reviewed the mechanism, the com-mon treatment methods, and neuromodulation theray of NDO after spinal cord injury, and elaborated percutaneous posterior tibial nerve stimulation, pudendal nerve regulation and the sacral neuromodulation respectively.

Objective To investigate the effect of vascular endothelial growth factor (VEGF) on the leukocyle function in a rat denervated infect flap model and to investigate the action mechanison of VEGF in the flap anti-infection .Methods An island pedicle flap measured 2 cm × 2 cm was raised on the right abdomen of sixty wister rats ,which were divided into three groups .All flaps re-ceived intradermal inoculation of 107 Staphylococcus aureus ,and the animals were observed for 96 h .The indexes of the leukocyte count ,leukocyte vitality ,hemiluminescence of neutrophils ,tissue bacterial count ,naked eyes observation of falptissue and the light microscope observation were detected .Results The leukocyte count in the exudation at postoperative 96 h had no statistical differ-ences among 3 groups(P>0 .05);while in the indexes detection of the leukocyte vitality ,chemiluminescence of neutrophils ,tissue bacterial count ,etc .,the comparison between the chronic denervated group and the control group showed very significantly differ-ences(P<0 .01);the differences between the VEGF treatment group and the chronic denervated group was very significant (P<0 .01) .The falp pathological change in the control group and the VEGF treatment groups was slight .Conclusion The soft issue af-ter losing the innervation decreases the leukocyte function .VEGF might improve the flap micro circulation and play an important role in improving the leukocyte function .

Objective:To analyze the clinical data on hospitalized spinal cord injury patients with calf muscle vein thromboses (MCVTs) seeking prevention and treatment techniques.Methods:The medical records of 423 patients with spinal cord injury were collected. Those with MCVT constituted the observation group, while those without served as controls. Their clinical data were compared.Results:The risk factors for MCVT were screened in logistic regression analyses. The results showed that age, an ASIA grade of A or B, spinal fusion, preventive anticoagulation, physiotherapy treatment and a homocysteine level >15μmol/L were risk factors for the occurrence of a MCVT.Conclusions:Age, an ASIA grade of A or B, spinal fusion or an elevated serum homocysteine level are all risk factors for MCVT. Active anticoagulation and physical therapy may reduce the risk.

Objective To explore the factors related with bladder function after surgical intervention in patients with first lumbar burst fractures uniting isolated conus medullaris syndrome (CMS). Methods 25 patients complicated CMS in 618 patients with L1 burst fracture were analyzed retrospectively. Results The recovery rate of patients with saddle sensation weakness was higher than the patients with saddle sensation disappeared (P<0.05). There was no difference in bladder function between patients accepted surgery within 2 weeks and more than 2 weeks (P>0.05). Conclusion Saddle sensation before surgery related with the recovery of bladder function.

Objective To evaluate the efficacy of intravertebral augmentation which including transpedicular bone graft, transpediclebody augmenter and vertebroplasty in preventing the correction loss and implant failure of short-segment pedicle instrumentation for thoracolumbarfractures through meta-analysis. Methods Experimental studies (randomized controlled trails, non-randomized controlled trails)and observational studies (cohort studies, case control studies) related with application of posterior short-segment pedicle instrumentationwith intravertebral augmentation for thoracolumbar fractures were searched from Pubmed, EMBASE and CNKI according to the inclusionand exclusion criteria, and hand-searched in Chinese and English journals. RevMan 5.0.18 provided by Cochrane was used to analyse the data.Results 1 randomized controlled trail and 7 observational studies were included. There were 442 patients, in which 216 patients werewith and 226 patients without intravertebral augmentation. There was no significant difference in correction loss and risk of implant failurebetween these two groups. Conclusion Intravertebral augmentation does little about the risk of correction loss and implant failure associatedwith posterior short-segment pedicle instrumention for patients with thoraculumbar fractures.

Objective To investigate the effect of basic fibroblast growth factor (bFGF) on the synthesis of extracellular matrixc (ECM)and expression of chondromodulin in human intervertebral disc cells. Methods 4 intervertebral discs (IVDs) obtained from patients in thetreatment of disc degenerative disease were used for cell culture. The secondary generation of intervertebral disc cells were cultured for 7days, then different concentration of bFGF (0, 0.1 ng/ml, 1 ng/ml, 10 ng/ml)were added to the medium and treated for 72 hours. Real-timeRT-PCR was used to detect the change of Aggrecan and type Ⅱ collagen mRNA expression. The effect of FGF on the expression of ChM-1,a cartilage derived anti-angiogenic factor, was also used by means of Real-time RT-PCR and Western blot. Results Real-time RT-PCRshowed that bFGF can significantly inhibit the expression of Aggrecan and type Ⅱ collagen mRNA. Both Real-time RT-PCR and Westernblot showed that the expression of ChM-1 was down-regulated by administration of bFGF with dose-dependent way. Conclusion bFGFserves primarily as a catabolic factor and induce the angiogenesis in the process of intervertebral disc degeneration.

Objective To explore the effects of rehabilitation for adult cervical spinal cord injury without radiological abnormality. Methods 80 patients were studied retrospectively. Results The increase of motor score of anterior, posterior and conservative group were around 5, 2 and 2, whereas that of FIM were 11, 17 and 15, respectively. The changes of sensory score were uncertain.Conclusion The effect of surgical or conservative treatment is limited on neurological recovery, while rehabilitation can bring more functional independence to patients with cervical spinal cord injury without radiological abnormality.
10.Research progress on exosome-derived non-coding RNAs in liquid biopsy of hepatocelluar carcinoma
Journal of International Oncology 2019;46(6):378-381
Exosomes contain ample non-coding RNAs,which mainly function as regulating gene expression and play key roles in the occurrence and development of hepatocellular carcinoma.Exosomal non-coding RNAs are expected to become a new biopsy marker for hepatocellular carcinoma,providing a new means for early diagnosis and early treatment of hepatocellular carcinoma.Although the clinical application of exosomal non-coding RNAs is still insufficient at present,exosomal non-coding RNAs will play an increasingly important role in the diagnosis,personalized treatment and prognosis evaluation of hepatocellular carcinoma with the deepening of research.
